    Abstract: A shape memory material inductive heating arrangement comprising an array of coils capable of carrying an alternating electrical current and generating a magnetic field, a shape memory element having a first modulus and a second modulus, the second modulus greater than the first, characterised in that the array of coils and shape memory element are in effective range so that when an alternating current is passed through the coils the shape memory element is subject to the magnetic field and heated thereby, the induced heat sufficient to change the modulus of the shape memory material from the first to the second modulus.

    Abstract: A hemostatic clip for application to body tissue is disclosed which includes opposed leg portions connected by a bail portion with each leg portion having a tissue contacting surface defined thereon. A pair of projections and a pair of recessed areas are defined on each tissue contacting surface and are disposed in an alternating arrangement such that the movement inhibiting structures on one leg portion are in juxtaposed alignment with those on the opposed leg portion.
